In a telecom line card or power supply output, this typically covers secondary lightning surge protection per GR-1089 or ITU-T K.20 when paired with a primary GDT or PTC. The bidirectional configuration means polarity reversal on the protected line does not matter — the TVS clamps symmetrically in both directions. ## Active lifecycle and compliance posture Compliance documentation including RoHS and REACH declarations is available from the manufacturer; the part does not carry power line protection, so it is intended for signal or DC rail surge clamping rather than AC mains input.","metaTitle":"1.5SMC39CA V7G TVS Diode, 1500W, 33.3V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC39CA V7G bidirectional Zener TVS, 1500W peak pulse power, 33.3V reverse standoff, 53.9V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Taiwan Semiconductor Corporation","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Telecom","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC39","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMC)","Voltage - Breakdown (Min)":"37.1V","Voltage - Clamping (Max) @ Ipp":"53.9V","Voltage - Reverse Standoff (Typ)":"33.3V","Current - Peak Pulse (10/1000µs)":"29A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC39CA%20V7G/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/taiwan-semiconductor-corporation/1.5SMC39CA-V7G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/taiwan-semiconductor-corporation/1.5SMC39CA-V7G when reusing this data.
